I I Thebolt cage A as particularly shown in Be it knownthat we,Wn.LIAM J Fnnisonlinnn' and HERBERT RICHARDSON, citizens of theUnited States, and'residents of Pontiac, finjthe county of Oakland andState of Michtjgah, have made certain new and useful Impifovemen'ts inDoor-Locks, of which the fol- 1 'owing-isa specification.

V Our present invention relates to door 1Q jlocks,.and more particularlyto-a lock adaptfor automobile-doors, our'object ing to "provide asimple, strong and durap le arra ng'ement ,embodyin'g a minimum numberfof parts so 006 crating as to prevent the l5' d'oorifrom ratthng whenclosed, and so arm ranged and-constructed'as to promote'ccn.

tain advantages in theiroperation and ap- "jplifca'tionlb an automobile.door as hereinaf- "iter specifically referred'to. These and otherpbjectsiwill be ap" arent from the followin g .1 ,l description, in-wich reference is made to the accompanying drawingsforming a part orthisspecification and in which, Figure 1 is 'a-perspecti've view of theinter- 'jihediate portion of a'motor vehicle, illustratoilr improvedlock'in connection with one of the doors thereof. Fig. 2 is an insideelevation of ad'oining-parts of the door and gframe, partly roken awayand in section. Fig. .3 is an end elevation of the bolt cage {an theparts connected thereto. Fig. 4 is ja'perspective view of'the bolt cagewith its jconriected parts removed. Fig. 5 is a similar iiiew of thebolt removed. 'Fi 6 is a similar view of the 'bolt' actuating ieverremoved. 'Fig'. 'Tis a similar view of the striker plate. Fig. 8 is asimilarview of one of the con-. trolli rings, Fig. 9 is an elevationpartly ro en away and in section and illustrating a; slightly modifiedform of actuating member, and Fig. 10 is a sectional view Figs. 3 and 4,is provided with a longitudinal slot cut therein from its lower edge andin which is disposed the locking bolt E, this bolt, as will be seen byreference to Figs. 3 and 5, being square in cross section for the majorportion of its length so as to fit and move without friction in the slot(1. of the bolt cage, the free projecting end portion 0 of the lockingbolt being reduced to a triangular shape with a lower inner roundedsurface in order to successfully ride the striker plate; L

The rear end of the locking bolt E is provided with a vertical slot 6'in line with a similar slot a? of the bolt cage and this end ofthe-locking bolt is also provided with horizontal apertures 0 adapted toregister with similar apertures a of the bolt cage in order to receive apivot pin 1 by which the rear end of the locking bolt pirotally-mountcd, and upon which pix ot. its forward reduced end a is movablevertically by means to be hereinafter described.

At its forward end the bolt cage is provided with an intermediate heada. extending trmisvcrsely of the (entire width of the cage, this headtapering toward the inner side of the bolt cage by virluc oi its upperand lowei inclined surfaces. and being: intersected by thebci'ore-inci'nioned longi= idinal slot a of the bolt cage in order toallow the locking bolt E to be raised. so that its reduced head 6 isbetween the said tapering edges of the projecting head.

The striker plate C is provided upon its outer surface with upper andlower pri'ijcctions c and 0", the lower and upper faves of: whichprojections, are. inclined and spaced from one another in order toprovide a tapering space of substantially the proporthrough the boltcage illustrating anothertions of the "head at of the bolt cage, thisslight y modified form which a horizontapering space receiving the saidhead of the tally dis osed handle is utilized to actuate the lock olt.

Referring now bolt cage and the lower projection 0 having anintermediate and substantially triangular cavity 0 into which thereduced free end of the bolt E projects to lock the door in closedosition. Thus, it will be seen that the striker plate keeper as well,and that proper engagement as above stated of the head a of the boltcage within the triangular recess or space between projections c and a,will effectually prevent up and down movement of the door to thesefigures, the bolt cage A is set into the free edge of the door B,adjacent the upper end of the latter, and the striker plate C isset-into the adjacent edge of the door frame D, the said bolt cage andstriker being secured in position by suitable fastening membersextending through their projecting apertured ears (1,0 respec tively. I

C forms a bumper and a B, and thus cooperate with the locking bolt inengaged position to prevent the door from rattling during the travel oftheve hicle.

As shown in Fig. 10, .we may actuate the locking bolt E by means of ahorizontal spindle G having intermediate side projec-- tions within theboltcage and between-portions of the bolt and having-a handle G eitherupon the inside or outside ofthe door B, but we prefer to utilize anactuating leiver H, the vertical body portion of I hich is extendedwithin and through the r ar vertical slot a, e of-the bolt cageandlocking bolt, and pivoted by virtue of the pin F extending through itslower aperture h, the lower extremity of this vertical body portion ofthe lever having an angular arm h' which extendsforwardly beneathwhe"locking bolt, whereby'angular movement'ot the upper portion of thelever'in a direction away from the door frame serves to. raise thelocking bolt and release the door.

W'e. preferably -control the normalfposi tion of theparts by means of aflat spring I secured within the longitudinalsl ot .ofvthe bolt cage andbearing downwardly upon the locking bolt E as particularly -sh im inFigs and prevent the lever from attling by means of a small coil springeatedin-the 1slot d et the back cage and engaging the ever. 1

The vertical portion of the lever H may be disposed within a cut-outportion in the inner face of the door as particularlyshown in Figs. 1and 2, and, as also shown in,-thisfigure. its upper end may have anangular inward extension 11- constituting a handle by which it may bereadily manipulated. As shown in Fig. J, however, the upper portion of acorresponding lever H may beprovided with an inclined vertical edgeehfiand a push vrod J may be vertically m0vably mounted through the upperedge of the dew-,tlxis push rod having an upper button j and controlledby a spring 1" and having its "lower end in engagement with the inclinededge of the lever so that When-dea, pressed, the lever will be rocked toraise the v locking bolt.

We claim: 1. In an' automobile door lock, the combination of. a strikerplate having a tapering side recess and a cavitybelow the recess; of abolt cage havin a. tapering headprojecting fromone end. and adapted'tofit within the -sid'recess ofthe striker plate, said bolt cage alsohaving a longitudinal slot extending partially through the said head,alocking I bolt pivotally mountedwithin the slot of the bolt cage andhaving a projecting free end extending beyond the headed end of the boltcage and movable into and: out of the slot of the head,fand meansforjinovin'g the said locking bolt,ja ll for the purpose described.

2. In an ta-utomobile door lock, the combination with a striker platehaving a tapering side recess andjnli cavity below the recess,' of abolt cage having a projecting tapering head at one end 'adapted to'interfit the recess ,of thestriker plate,"a locking .bolt movablewithinthe'boltica'ge and into i .hlld out-of\the.
